TYPEWRITING-MACHINE.

Specification of Letters Patent. Patented 25 1920 Application filed July 3, 1918. Serial No. 243,116.

To all whom it may concern:

Be it known that I, JOHN VVALDHEIM, a citizen of the UnitedSta'tes, residing in Elizabeth, in the county of Union and State of New Jersey, have invented certain new and useful Improvements in Typewritin'g- Machines, of which the following is a specific ation.

My invention relates .to typewriting machines of the class wherein a plurality of separate and distinct printing mechanisms or devices are provided, any one of which may be operated .by a single set of key levers and from a single keyboard; so that a plurality of fonts of type differing in style from one another, .or fonts of type adapt-- certain improvements in and relating to typewriting machines of the type or class above referred to, the invention to which this present application relates being an improvement upon, the typewriter disclosed in my co-pending application, 20, 1918, Serial No. 223,489. 7

In the present application there is provided a plurality of printing devices, preferably in the form of type-sets,'each comprising a. type-segment carrying a pluralityof pivotally supported type-bars, said printing devices being supported in fixed relation to each other from and by the main frame of the machine, so that the main frame and the printing devices form a unitary structure; the printingmechanisms, each colle'ctively considered, being held in fixed and unchanging relation with the main frame and with each other.

Supported by and movable relatively to themain frame of the'typewriter, is a supplemental frame,'which carries aset of key levers, whereby any one of the printing .devices may be operated,'.a carriage for supporting a work-sheet to be typed upon, and

means for regulating and controlling the movement of the carriage to secure a proper spacing of the characters impressed upon the WOI'k-Sllt; the supplemental frame together with the key levers, the carriage, and

the elements concerned with the movement thereof, forming a second unitary structure movable relatively to the main frame and to the printing devices supported thereby, in order to bring a worksheet carried by the carriage into positions such that it may be typed by any one of said printing devices, and into positions such that the particular printing mechanism selected for use niay be operated by the key levers.

The various elements and groups of elements carried by. the supplemental frame are therefore held in permanent relation to one another, and move in unison relatively to the stationary printing mechanisms carried by the main-frame of the machine; the printing mechanisms being arranged side by side and the movement of the supplemental frame taking place in a direction parallel with the axis of a platen carried by-the carriage.

The supplemental frame carries escapement mechanism for regulatingthe movement of the carriage for letter-spacing. Suitable line-spacing mechanism for rotating the platen may also be provided, which mechanism, however, is not illustrated in detail herein. A single escapement is'used,

but each type-set is shown as provided with a separate universal bar, segmental in form and pivotallysupported from the type-bar supporting-segment thereof; the escapement mechanism being brought into position so that it may be operated by the universal bar of the'particular type-set selected for use as the supplemental frame is moved to bring the type-set in question;

Y The escapement mechanism is shown as operated through an intermediate reciprocating member with which the nniversal bar engages; and suitable ribbion supporting and feeding mechanism may be also em played. I

Motionmay be transmitted from the key mediate levers operatively connected with "the type-bars, a set of intermediate levers being provided for each separate type-set.

The key levers-are moved into operative relation with the set ofintermediate levers associated with the type-bars of the typeset selected for use by moving the supplethe key levers-into operative relation with levers to the-type-vbars through sets of intermental frame, as above explained; and suitable locking mechanism is shown as provided for locking the supplemental frame in positions to secure the proper operation of each type-set, and for .releasing the same when it is desired to change to and towrite with anothertype-set.

. Other features and advantages will hereinafter appear.

In the accompanying drawings, Figure 1 is a skeleton view illustrating my improved typewriting machine in perspective.

' main frame shown in aconventional manner in the drawings as comprising two sidemembers 4, the rear ends ofwhich are connected with one another by means of a cross connecting member 5, and the front ends of which are connected by a bar 6 which als serves as a track for supporting the from end of a supplemental frame, which carries the movable key levers and the work-sheet supporting and advancingmechanism of the typewriter; the cross-connecting member 5 whereby the rear ends of the side members 4- ends of'the side me are'connected with one another being pro.- g ided with guides 7 for guidin the rear end of the supplemental frame w ich supports the ke ,levers and'work-sheet supporting .and a vancing mechanism as said frame is moved relatively to the main frame.

'The reference numeral 8. designates the movable supplemental frame as a whole, the same comprising two side members 9, the front ends of which are connected with one another by a bar 10, and the rear ends of which are-connected with a bar 11, the edges of which are provided with guides 12 located adjacent the guides 7 in the main frame of the machine, suitable balls 13 be-' ing commonly interposedin order to reduce friction. Extending upwardly from the rear m ers 9 of the movable frame are standards 14 which support the carriage 15 of the typewriter, the escapement mechanism for controlling the move-' ment thereof, and other elements, as will- 7 hereinafter appean,

The front end of the supplemental frame V. is supported by the front cross bar'or rail 6 above referred to, suitable rollers 16 being preferably journaled *in the side members of the frame to reduce the friction between r the parts, The supplemental frame, above referred to, carries and serves as a sup ort' for a set of operating keys which CODStltllf-Q' the keyboard of the machine, for the carriage 15 whereby the platen 17 is carried, as well also as for the escapement mechanism and the mechanism for shifting the platen into its upper and'lower-case positions, all of which sets of mechanisms are connected the movable frame made up 'of the members 9, 10, and 11, and move in unison therewith. The front end of the carriage is supported by a cross rail 18 extending between the side members 4 of the main frame of the ma-' chine, and the rear end of the carriage is supported by and moves along a rail 19 supported at the upper ends of the standards 1 1; the carriage being ordinarily moved by means of a spring drum operatively conin fixed relation with one another and with nected-therewith, but which is notshown in the drawings.

The reference numerals 20 designate two separate and independent printing or typing mechanisms supported from themain frame of the machine and held in fixed relation therewith and with one another, said printing mechanisms being shown as comprising type-sets secured to and supported by a bar 21 which extends between the-side members 4 of the main frame, and'the ends of which are permanently secured thereto. These type-sets each comprise a type-bar supporting segment 22, which segments are secured to the cross bar 21; and 23 designates typebars, a portion only of which is shown, said type-bars being pivotally secured at 24 within slots 25 provlded in said segments. The type-bars 23 are operated to move their freeends into contact with a work-sheetextend' ing about the platen 17 by means of bellcrank levers 26, one for each type-bar, the,

upper ends of said levers being operativel connected with thet e-bars by a: pin-an slot connection 27. hese-bell-crank levers are themselves pivotally s1 ported at 28 in a slotted bar 29extendin 'hetween andthe ends of which are secure to the sidemembers 4 of the mainframe of the machine.

Thebell-crank levers 26 are operated by means of a series of levers30, the rear ends of which are pivot-ally sup orted at 31in a1 slotted bar, 32 extending tween and'the ends of which are connected with the side of said levers bein 'guidediby a slotted guide 33, theends 0 which are also secured to the side members 4. The levers 30are operatively connected with-the forwardly-ex tending arms o-f'the' bell-crank levers26 b pin-and-slot connections 34, from which it follows that downward movement imparted to the forward ends of thesaid levers will operate the type-bars 23 through the bellcrank levers-26. The free ends of the typemembers 4 of the main frame, the front ends bars 23 are supported in type-baskets 34 when in their lowermost position as shown,

one such basket being provided for each type-set; and guides '35 for guiding the free bars of each type-set, although a part only of said levers, as well as of the type-bars themselves, are shown in the drawings.

The supplemental frame 8 serves as a support for a plurality of key-levers 36, part only ofwhich is shown, the forward ends of which levers carry keys 37 which constias we tute the keyboard of the machine, and the rear ends of which levers are pivotally supported on a rod 38. and in slots provided in a forwardly-projecting rib upon therear connecting bar 11 of. the supplemental frame; the key-levers being. guided adjacent their forward ends by a slotted guide 39 extending between the side members 9 of the supplemental frame.

The key-levers 36 are each provided with upwardly-extending portions terminating in hooks 41, which hooks may be brought into position above either set of operating levers 30, which operate the type-bars of their associated printing mechanisms or type-sets above referred to,,bymoving the supplemental frame to one .side or the other of the main frame of the machine; whereupon, and as the key-levers are depressed, the type-bars ofthe particular typeset selected for 'use may. be operated. It

will be appreciated thatas the supplemen- .35

tal frame is moved from side to side, the carriage V l as the escapement mechanism, w1ll move with the keyboard, as said elements are supported .ifrom the. upwardlyextend ing standards 14 which form a part of the w supplemental ,r-frame and move in unison therewith, as above explained.

To lock' jthe supplemental frsime and keylevers and work-sheet supporting and adther'eby in type-sets m'ay. be operated by the single set of key-levers.- I provide suitable locking mechanism; the'same being shown as com-' prising a swinging locking pawl 42 pivotally supported in lugs 43 carried by the rear "connecting bar 11, and the free end 44 of which pawl is adapted to enter either one of two" slots 45 provided in therear cross bar 5 of the 'main frame of the machine,

said pawlbeing operated through aconnecting link 46,'the ends of which are opera-v tively connected with said pawl and ,with

the lower end of anarm 47 carried by a rockshaft 48 supported inlbearings provided in the sidemembers '9 of the supplemental frame,;-said rock-shaft being oper'atedby an arm 49 located at either side of thekeyboard of themachine. The arm- 49-is-shown asiheld iii-its forward position and against 15 and platen 17 carried thereby,

a suitable stop by means of a spring 50, the effect of which is to hold the free end 44 of the pawl 42 in engagement with. a slot 45. Preferably a smooth rib 51 is provided which extends between the slots '45, so that after the pawl 42 has been moved out of engagement with the slot 45 and the supplemental frame moved slightly, the free end of the pawl may be permitted to rest uponstops 45* against which ployed, although only one is shown, which v members aresupported by a shaft 53 supporte'din bearings provided upon the standards 14, and the forward ends of which members carry a shifting rail 54 through which vertical movement is transmitted tothe'platen 17 tomove itinto its. upper and lower-case positions; said rocking members 52 being operated by shift levers 55 carried by the supplemental frame, and which shift levers transmit motion to-the rocking'menn bers through upwardly-extending arms 55,

the free ends of which engage said members, from, which it will be observed that the mechanism for shifting "the platen into its upper and lower-case positions is carried by and moves with the supplemental frame,

and is always in position to be operated by.

v the arms 55 carried by said frame.

Carried by the rear ,connecting member 11 is a bracket 56 which serves as a support for the escapement mechanism for regulating the movement of the carriage, which" mechanism, therefore,"partakes of the move ment of the supplemental frame 8.

The escapement or letter-feeding mechanism itself may be of' any suitable form.

As shown, however, said mechanism comprises fixedand movable dogs 57, 58 carried by a dog rocker 59, and which dogs are T adapted to engage the teeth of an escapement wheel 60 supported by the bracket 56; said escapement'wheel being geared to the carriage'15 through a pinion'fil'in engagemerit with a rack 62 pivotally mounted on, the carriage 15. The dogs 57 and58 are operated by means of a reciprocating intermediate member'63 pivotally supported by a link 64 and arms 65 carried by a pivotally supported rocker, ,in order that its movements may be maintained parallel, which in-';

termediate member is operatively associated with the dogs.

. The forward of the reciprocating member 63 is engaged. and moved reen the type-sets 20 and lying within grooves provided in the rear sidesof the segments.

22, one of said bars being shown at 66, Fig. 2. These universal bars are supported from the rear sidesiof the segments in such a way that they will be maintained parallel as they move toward and from, the segments, and in such a way as to reduce friction to a minimum, by means of bell-crank levers 67 68;

the longer/arms of which are pivotally con- .nected with the universal bars, while the shorter arms are connected with one another through links 69, a pair of such bellcrank levers 67 being preferably provided at each end of each universalbar and one, bell-crank lever 68 near the middle of saiduniversal bar. This parallel mechanism is not illustratedin detail 'in the drawings accompanying this application, as the -same may be identical in construction and operawhich it will be appreciated that as the supplemental frame '8 is moved from side to side of the main frame'of the machine, the

reciprocating member 63 will be moved therewith, and will be brought into positions adjacent one or the other of the bars70 of the universal bars of the two type-sets, so that motion will be transmitted to the single es'capement mechanism of the machine by the universal bar of the particular type-set or printing mechanism selected for use.

The reciprocating member 63, in addition to being operable by the universal bars 66 as above pointed out, may also be operated through a depending arm 71 of the rocker which carries the arm 65, said arm 71 being engaged by'a finger 7 2 with which the spacebar 73 of the keyboard is operatively connected, to thereby provide for spacing the carriage between .words or independently of the typeset s. The connections intermediate the space-bar and the reciprocating member 63 comprise a lever 73 pivotally supported on the rod 38. v v The end portions 4 of the main frame of the machine should permit the ends of the connecting bar 11- to move beyond them, to

which end they are shown as providedwith' j openings 74 so located, and of'suclfa size This feature provides for ,a. reduction in width of "the main frame of the .machine. 1 and necessitates the use of a main frame of that the ends of the connecting-bar of the supplemental frame may extend 'therethrough when said frame is in either one of,

its extreme positions, as shown in Fig. 3.

a width no greater than one corresponding improyements may be used without others.
